An early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was to protect lighting circuit wiring from accidental short circuits and overloads.
The solution was the fusee, a device that spread the force exerted by the unwinding spring in a more even manner. It is thought that the fusee was invented by Jacob Zech of Prague, however others think that it was Leonardo DaVinci that first came up with the device. Da Vinci is credited with a drawing of such a mechanism in manuscripts dated around 1485. It was Galileo Galilei that first studied the motion of the pendulum in 1602. His studies were followed later by Christiaan Huygens, who patented the first clock using the device.
